MOSCOW, May 5. /TASS/. At least seven people were killed in the shooting in the Serbian village of Dubona in the Mladenovac municipality late on Thursday, the Vecernje novosti newspaper reported.

A total of 13 people, including children, were injured.

According to the newspaper’s sources, the suspect has been surrounded by police forces, but refuses to lay down his weapons and keeps shooting at officers who are trying to detain him.

Six children and one teacher were injured and are now in hospital. According to Serbian media reports, the 13-year-old shooter came to the school with two Molotov cocktails and two handguns.
